Gnawed

Rats have gnawed holes in the door.

The dog gnawed the mutton bone his owner had thrown him.

Horned toads hopped about; each of the four upper corners of the room was festooned with a thick cobweb, in the center of which sat a spider as big around as a washbasin, and armed with pincher-like claws; a red-and-green lizard was stretched at full length on the window-sill and black rats darted in and out of the holes they had gnawed in the floor of the cottage.
